How to thermally insulate a house and save

To protect your home from cold and heat it is best to have a good thermal insulator. Unfortunately in most homes the insulation available is insufficient, so in this post I want to explain the different insulation systems.

There are companies specialized in carrying out this type of work. This is the case of Hormuk, a company specialized in the installation of the SATE system on facades.

But what is this SATE? We will see this and other methods in more detail throughout the post.

SATE System

When we talk about the SATE system we refer to an External Thermal Insulation System. Basically it is about isolating the house but on the outside of it.

It is the best method to insulate most buildings, as it offers very good results in terms of energy efficiency.

To achieve this, a series of layers are placed on the outside of the façade responsible for thermally protecting the interior of the house.

In the initial layers we find the insulating materials, while in the outer layers materials are placed to waterproof and give stability to the structure.

What must be taken into account is that the exterior appearance of the house will be modified, but in return we do not lose useful space inside the home and we will obtain insulation without thermal bridges.

SATE Isolation

Exterior insulation with ventilated façade

The exterior insulation with ventilated façade is similar to SATE, but there is a considerable difference: it incorporates an air chamber located between the exterior cladding and the insulation layer.

Thanks to this camera you can evacuate the water without affecting the insulation layers, although you should bear in mind that its installation cost will be higher.

It can be a good solution for certain homes, but as a general rule it will be more advisable to opt for the EAS system.

In-camera injection

There is an intermediate solution between interior insulation and exterior insulation: it is chamber injection insulation.

This system consists of injecting insulation, either in foam or in the form of granules, in the air chamber that is in the walls of the houses.

It is the most economical and least invasive option, but you must bear in mind that the results will be of a lower quality than with the previous systems.

Perhaps due to lack of space or lack of budget may be the ideal option for you, but always keep in mind that you will not have a perfect finish.

However, if you can only apply this type of insulation you will achieve a significant improvement in the energy efficiency of your home.

Interior thermal insulation

Interior thermal insulation is the opposite of SATE: insulating materials are installed inside the house.

Here we can choose from a wide range of materials:

The mounting system will depend on the material used, since it can be made with metal profiles, using mechanical fixings or simply using adhesive.

As a positive part of the interior insulation we find that the interior appearance of the house will not be modified, but on the other hand we will lose useful space in the rooms.

In addition, as an additional problem, thermal bridges will still be present, so you do not get total insulation of the house.

This option becomes the best alternative in cases where regulations do not allow to alter the external appearance of the buildings.

Place the acoustic insulator

Sprayed polyurethane

The latter insulation system is frequently used in buildings whose façade has been exposed due to the demolition of the adjacent building.

It consists of adhering projected polyurethane to the entire façade to improve its insulating capabilities as much as possible.

It is a material that is applied extremely quickly and that resists very well to different weathers.

With this general review of the different systems to thermally insulate a house you will know what options you have available for your home.

This is a very interesting measure to reduce household energy bills. With good insulation you will not only save on heating, but you will reduce the use of air conditioning in summer.

It may seem like a somewhat high expense, but if you add up everything you are going to save on bills in the coming years you will see how it is a very profitable investment.

It will take some time to amortize it, but you will continue to enjoy the isolation for years and years. With all the savings that entails!
